NON-TRAUMATIC ECTOPIA LENTIS IN A PAEDIATRIC OPHTHALMOLOGY PRACTICE, IBADAN, NIGERIA

Non-traumatic ectopia lentis is a rare ocular disorder usually associated with syndromes like Marfans's syndrome, Weil-Marchesani and Homocystinuria. Ectopia lentis can lead to profound visual loss from refractive errors, glaucoma as well as retinal detachment if left unattended. The aim of this study was to describe the clinical profile of patients with non-traumatic ectopia lentis in a paediatric ophthalmology clinic in Ibadan, Nigeria. The clinical records of children ≤16 years diagnosed with non- traumatic ectopia lentis at the Paediatric Ophthalmology Clinic, University College Hospital Ibadan, from May 1, 2015 to Dec 31, 2019 were retrospectively reviewed. Information on demography, family history, visual acuity (VA), mean refractive error (spherical equivalent), and management was retrieved. Clinical records of 25 patients were reviewed. The mean age was 8.9 (±3.41) years with a range of 2-15 years. Sixteen (64%) patients were males. All the patients had bilateral involvement. A positive family history of ectopia lentis was elicited in 6 (24%) patients. Thirteen (52%) patients had a Marfanoid habitus and superior displacement of the lens was observed in 26 (52%) eyes. The presenting visual acuity was
